WebFeb 28, 2024 · The centrifugal pump curve tells us that the NPSH required at 425 gpm = 20’. If the vapor pressure of the liquid is less than 1 atmosphere minus the NPSH required, it will be a suitable application. Using 30’ = 1 atmosphere to be conservative, this pump will handle any liquid at 425 gpm which has a vapor pressure less than 10’.
